editing of passage for Year 3 students

One afternoon, Mrs Tan, her daughter and their neighbour, Mr Lau, were waiting for the lift. When the lift arrived they went in and pressed the button for the third floor.

When the lift reached the third floor it suddenly stopped moving, but the door did not open. Mrs Tan and her daughter were very frightened, but Mr Lau was not. He advised them to remain calm and to not be scared. He pressed the emergency button repeatedly and then assured them that help would come soon. On hearing what he said, Mrs Tan and her daughter were no longer afraid. A neighbour ,on hearing the emergency bell ring, phoned the lift maintenance section to report that some people were trapped in the lift.

A few minutes later a lift technician arrived and told the people trapped in the lift to remain calm, and that "the lift will be opened soon". The technician managed to get the lift open in about ten minutes. When the lift door opened, Mrs Tan, her daughter and Mr Lau were relieved. They thanked the technician for rescuing them.

(That's how I would write it. Don't know if it's more correct than the initial way, but to my ears it flows a little better)

Thanks, Cyracuz.
